The interrupt enable register A is used by the host processor to mask unnecessary interrupt sources. Bits
loaded with a 1 allow the corresponding interrupt condition to generate an interrupt on the external pin.
Conversely, bits loaded with a 0 mask the corresponding interrupt condition from generating an interrupt
on the external pin. This register only affects the interrupt on the external terminal, it does not affect the
bits in interrupt status register A. A given condition can set the appropriate bit in the status register and not
cause an interrupt on the external terminal. To determine if this device is driving the interrupt terminal
either perform a logical AND of interrupt status register A with interrupt enable register A, or check the
state of the interrupt A bit in the interrupt configuration register at address C2h.
